[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The anesthesia device for adjusting the concentration of anesthetics described in the present invention uses a pump body 1 to extract the solvent in the solvent bottle into the anesthesia mixing box, and the extraction amount is controlled by a flow meter 1. The anesthetic in the anesthetic bottle can be extracted into the anesthesia mixing box by a pump body 2, and the extracted anesthetic amount can be controlled by the pump body 2. After the solvent and anesthetic are extracted into the anesthesia mixing box, the motor 1 is started to drive the spiral blade and the stirring blade to rotate, so that the solvent and the anesthetic are evenly stirred, and the concentration of the mixed liquid is measured by a concentration sensor. When the concentration does not meet the requirements, the solvent or anesthetic is continuously added until a specific anesthetic concentration is reached, thereby making it easier to adjust the anesthetic concentration.

In the aerosol mixer, the atomized anesthetic solution and oxygen are mixed more evenly, avoiding the adverse effects on the patient caused by uneven mixing, and ensuring the normal progress of anesthesia.

With the cooperation of a fixed rod, an adjusting rod and a pushing plate, the patient's head can be confined within an enclosure range, so that the mouth and nose can be more accurately and stably aligned with the mask body. Moreover, when the pushing plate contacts the patient's body, the motor 4 can be started to drive the two-way threaded rod to rotate, so that the pushing plates on the upper and lower sides can slide simultaneously and move away from each other, and the wrinkles of the clothes can be pushed aside, so that it can be more intuitive to judge whether the end of the pushing plate fits the patient's body. Moreover, with the cooperation of the sliding column and the spring, a certain degree of buffering can be achieved to avoid damage to the patient's skin. The expansion plate can be inserted into the patient's mouth, and then the motors 3 on both sides can be started to drive the threaded rod 2 to rotate, so that the two expansion plates can slide simultaneously and move away from each other, so that the patient's mouth can be slightly opened, so as to avoid the situation where the patient's teeth bite the tongue due to the closure of the patient's mouth when the patient enters anesthesia.

A pump body 2 12 is connected, the liquid outlet end of the pump body 2 12 is connected with a pipeline 1 11, the left end of the pipeline 1 11 is connected with the anesthesia mixing box 2, a pump body 3 14 is fixedly connected to the middle of the left side of the upper end of the anesthesia mixing box 2, the liquid inlet end of the pump body 3 14 is connected with the anesthesia mixing box 2, the liquid outlet end of the pump body 3 14 is connected with a pipeline 2 15, the left end of the pipeline 2 15 is connected with a hard tube 42, the left end of the hard tube 42 is connected with the cover body 24, and an adjustable enclosure mechanism is provided on the hard tube 42 to prevent the patient from breaking free of the cover body 24;

[0035] The adjustable enclosure mechanism includes a mounting plate 18 which is sleeved and fixedly connected to the hard pipe 42. The middle parts of the front and rear sides of the right end face of the mounting plate 18 are fixedly connected to a limit plate 22. A fixed rod 23 is slidably connected to the inner side of the limit plate 22. The fixed rod 23 is slidably connected to the adjusting rod 25.

[0036] In this embodiment, Figure 1 , Figure 6 , Figure 7 As shown, an oxygen cylinder 6 is fixedly connected to the middle of the right side of the upper end surface of the base 1, and an oxygen supply pump 5 is connected and fixedly connected to the middle of the upper end of the oxygen cylinder 6. The oxygen supply pump 5 is connected to an oxygen supply pipe 4 at the oxygen outlet end, and the left end of the oxygen supply pipe 4 is connected to an aerosol mixer 17, and the pipeline 15 is connected to the aerosol mixer 17;

[0037] An atomizer 16 is provided in the middle of the pipeline 2 15, and a flow meter 1 9 and a flow meter 2 10 are provided on the pipeline 3 41 and the pipeline 1 11 respectively;

[0038] A motor 3 is fixedly connected to the middle of the upper end surface of the anesthesia mixing box 2, a spiral blade 34 is fixedly connected to the output end of the motor 3, the upper end of the spiral blade 34 is rotatably arranged on the anesthesia mixing box 2, a stirring blade 35 is fixedly connected to the upper side of the spiral blade 34, and a concentration sensor 36 is arranged on one side of the bottom of the inner cavity of the anesthesia mixing box 2;

[0039] Specifically, the solvent in the solvent bottle 7 is pumped into the anesthesia mixing box 2 by using the pump body 18, and the pumping amount is controlled by the flow meter 9. The anesthetic in the anesthetic bottle 13 is pumped into the anesthesia mixing box 2 by using the pump body 12, and the pump body 12 can be used to control the amount of the pumped anesthetic. After the solvent and the anesthetic are pumped into the anesthesia mixing box 2, the motor 3 is started to drive the spiral blade 34 and the stirring blade 35 to rotate, so that the solvent and the anesthetic are evenly stirred, and the concentration of the mixed solution is controlled by the concentration sensor 36. The concentration is measured, and when the concentration does not meet the requirements, the solvent or anesthetic is continued to be added until a specific anesthetic concentration is reached, so that the anesthetic concentration can be adjusted more easily. When anesthesia is required, the anesthetic solution is extracted by the pump body 3 14, and enters the atomizer 16 through the pipeline 2 15, and then the oxygen in the oxygen cylinder 6 is extracted by the oxygen supply pump 5, and reaches the aerosol mixer 17 through the oxygen supply pipe 4. After the anesthetic solvent and oxygen are mixed in the aerosol mixer 17, they can be transported from the hard pipe 42 to the mask 24, and then the anesthesia work can be carried out;

[0040] Therefore, the anesthetic concentration can be accurately adjusted according to the concentration sensor 36, and the prepared anesthetic solution is stored in the anesthetic mixing box 2 and can be used multiple times without repeated preparation of the anesthetic solution, which is convenient for multiple anesthesia. In the aerosol mixer 17, the atomized anesthetic solution is mixed with oxygen more evenly, avoiding the adverse effects on the patient caused by uneven mixing, thereby ensuring the normal implementation of anesthesia.

[0041] In this embodiment, Figure 1-Figure 5 , Figure 8 , Fig. 9As shown, both ends of the right side of the mounting plate 18 are rotatably provided with a threaded rod 19, the threaded rod 19 is threadedly connected with a threaded block 20, and connecting rods 21 are rotatably provided on both sides of the right end face of the threaded block 20, one end of the connecting rod 21 is rotatably connected to one side of the fixed rod 23, and a motor 5 43 is fixedly connected to the middle part of the upper side of the right end face of the mounting plate 18, and the output end of the motor 5 43 is fixedly connected to the upper end of the threaded rod 19;

[0042] A gear 27 is rotatably arranged in the middle of the fixed rod 23, and the gear 27 is meshed with the tooth block on the adjusting rod 25. A motor 26 is fixedly connected to the lower end of the middle of the fixed rod 23, and the output end of the motor 26 is fixedly connected to the gear 27;

[0043] Two slide posts 28 are slidably connected to the left side of the adjustment rod 25, a fixed block 38 is fixedly connected to the right end of the slide post 28, and a push-off plate 37 is slidably connected to the upper and lower sides of the fixed block 38;

[0044] A spring 29 is sleeved on the sliding column 28, and both ends of the spring 29 are fixedly connected to the fixing block 38 and the adjusting rod 25 respectively;

[0045] The left end of the push plate 37 is threadedly connected with a bidirectional threaded rod 40, the upper end of the bidirectional threaded rod 40 is rotatably arranged on the fixed block 38, and the middle part of the upper end surface of the fixed block 38 is fixedly connected with a motor 4 39, and the output end of the motor 4 39 is fixedly connected to the upper end of the bidirectional threaded rod 40;

[0046] The left side of the hard tube 42 is fixedly connected with a groove plate 31 at both upper and lower ends, the groove plate 31 is slidably connected with an expansion plate 30, the right end of the expansion plate 30 is threadedly connected with a threaded rod 2 32, the upper and lower ends of the threaded rod 2 32 are rotatably arranged on the groove plate 31, and the middle part of one side of the groove plate 31 is fixedly connected with a motor 33, and the output end of the motor 33 is fixedly connected to one end of the threaded rod 2 32;

[0047] Specifically, when using the existing anesthesia device, an inhalation mask is worn on the patient's mouth and nose to allow the patient to inhale the anesthetic. However, when anesthetizing a patient with a mental disorder, the patient may frequently move his head due to non-cooperation to break free from the mask, thereby affecting the normal anesthesia work. In addition, since the behavior of the patient with a mental disorder is uncontrollable, the patient may bite his tongue during the anesthesia process.

[0048] Therefore, when the present embodiment is in use, the adjusting rod 25 is sleeved on the patient's neck, and according to the width of the neck, the motor 5 43 is started to drive the threaded rod 19 to rotate, so that the threaded block 20 moves up and down, and the fixing rods 23 on the front and rear sides can slide on the limiting plates 22 in different directions at the same time under the action of the connecting rod 21, until the fixing rod 23 fits the patient's neck, and then the motors 26 on both sides drive the gears 27 on both sides to rotate, so that the adjusting rod 25 slides on the fixing rod 23, and the opening plate 37 approaches the patient's neck, until the opening plate 37 fits the patient's neck, and then the patient can be adjusted with the cooperation of the fixing rod 23, the adjusting rod 25 and the opening plate 37. The head of the patient is confined within a range of the enclosure, so that the mouth and nose can be more accurately and stably aligned with the mask body 24. When the push-out plate 37 contacts the patient's neck, it is difficult to judge whether the push-out plate 37 fits the patient's body because the patient's clothes have a certain thickness. Therefore, when the push-out plate 37 contacts the clothes, the motor 439 is started to drive the bidirectional threaded rod 40 to rotate, so that the push-out plates 37 on the upper and lower sides slide simultaneously and move away from each other, and the wrinkles of the clothes are pushed away, so that it can be more intuitive to judge whether the end of the push-out plate 37 fits the patient's skin. In addition, with the cooperation of the slide column 28 and the spring 29, a certain degree of buffering can be achieved to avoid damage to the patient's skin.

[0049] When the patient's head is restrained, the mouth and nose can be placed in the mask body 24, and the expansion plate 30 can be inserted into the patient's mouth, and then the motors 33 on both sides can be started to drive the threaded rods 2 32 to rotate, so that the two expansion plates 30 slide away from each other at the same time, and the patient's mouth can be slightly opened to prevent the patient from biting the tongue due to the closure of the patient's mouth when the patient enters anesthesia;

[0050] Therefore, by utilizing the adjustable enclosure mechanism, the patient's head can be confined within an enclosure range with the cooperation of the fixing rod 23, the adjusting rod 25, and the dispersing plate 37, so that the patient's mouth and nose can be more accurately and stably aligned with the mask body 24, and when the dispersing plate 37 extends into the hair, the motor 4 39 can be started to drive the bidirectional threaded rod 40 to rotate, so that the dispersing plates 37 on the upper and lower sides slide and move away from each other at the same time, and the wrinkles of the clothes are pushed away, so that it can be more intuitive to judge whether the end of the dispersing plate 37 is in contact with the patient's body, and with the cooperation of the sliding column 28 and the spring 29, a certain degree of buffering can be achieved to avoid damage to the patient's skin, and the expansion plate 30 can be driven to be inserted into the patient's mouth, and then the motors 33 on both sides are started to drive the threaded rod 2 32 to rotate, so that the two expansion plates 30 slide and move away from each other at the same time, so that the patient's mouth can be slightly opened, so as to avoid the situation where the teeth bite the tongue due to the closure of the patient's mouth when the patient enters anesthesia.

[0051] Working principle: The solvent in the solvent bottle 7 is pumped out into the anesthesia mixing box 2 by using a pump body 8, and the pumping amount is controlled by a flow meter 9. The anesthetic in the anesthetic bottle 13 is pumped out into the anesthesia mixing box 2 by using a pump body 12, and the pump body 12 can be used to control the pumped anesthetic dosage. After the solvent and anesthetic are pumped into the anesthesia mixing box 2, the motor 3 is started to drive the spiral blade 34 and the stirring blade 35 to rotate, so that the solvent and the anesthetic are evenly mixed, and the concentration of the mixed liquid is measured by a concentration sensor 36. When the concentration does not meet the requirements, continue to add solvent or anesthetic until a specific anesthetic concentration is reached, so that it is easier to mix the anesthetic. The concentration is adjusted. When anesthesia is needed, the anesthetic solution is pumped out by the pump body 3 14, and enters the atomizer 16 through the pipeline 2 15. Then, the oxygen in the oxygen cylinder 6 is pumped out by the oxygen supply pump 5, and reaches the aerosol mixer 17 through the oxygen supply pipe 4. After the anesthetic solvent and oxygen are mixed in the aerosol mixer 17, they can be transported from the hard pipe 42 to the mask 24, and then the anesthesia work can be carried out; thus, the anesthetic concentration can be accurately adjusted according to the concentration sensor 36, and the adjusted anesthetic solution is stored in the anesthesia mixing box 2, which can be used multiple times without repeatedly adjusting the anesthetic solution, which is convenient for multiple anesthesia. In the aerosol mixer 17, the atomized anesthetic solution and oxygen are mixed more In order to ensure uniform mixing and avoid the adverse effects that uneven mixing may have on the patient, and to ensure the normal anesthesia, the adjusting rod 25 is sleeved on the patient's neck, and according to the width of the neck, the motor 5 43 is started to drive the threaded rod 19 to rotate, so that the threaded block 20 moves up and down, and the fixing rods 23 on the front and rear sides can slide on the limiting plate 22 in different directions at the same time under the action of the connecting rod 21, until the fixing rod 23 fits the patient's neck, and then the motors 26 on both sides drive the gears 27 on both sides to rotate, so that the adjusting rod 25 slides on the fixing rod 23, and the spreading plate 37 approaches the patient's neck, until the spreading plate 37 fits the patient's neck, and then the fixing rod 23, the adjusting rod 25, and the spreading plate 37 can be moved to the patient's neck. With the cooperation of the push-open plate 37, the patient's head is restricted within a surrounding range, so that the mouth and nose can be more accurately and stably aligned with the mask body 24. When the push-open plate 37 contacts the patient's neck, it is difficult to judge whether the push-open plate 37 fits the patient's body because the patient's clothes have a certain thickness. Therefore, when the push-open plate 37 contacts the clothes, the motor 439 is started to drive the bidirectional threaded rod 40 to rotate, so that the push-open plates 37 on the upper and lower sides slide simultaneously and move away from each other, and the wrinkles of the clothes are pushed away, so that it can be more intuitively judged whether the end of the push-open plate 37 fits the patient's skin. In addition, with the cooperation of the slide column 28 and the spring 29, a certain degree of buffering can be achieved to avoid damage to the patient's skin.When the patient's head is restrained, the mouth and nose can be placed in the mask body 24, and the expansion plate 30 can be inserted into the patient's mouth, and then the motors 33 on both sides can be started to drive the threaded rods 32 to rotate, so that the two expansion plates 30 slide simultaneously and move away from each other, and the patient's mouth can be slightly opened to prevent the patient from biting the tongue with the teeth due to the closure of the patient's mouth when the patient enters anesthesia; thus, the adjustable enclosure mechanism can be used to restrict the patient's head within an enclosure range under the cooperation of the fixed rod 23, the adjusting rod 25, and the opening plate 37, so that the mouth and nose can be more accurately and stably aligned with the mask body 24, and the opening plate 37 can be extended to the hair. During the operation, the motor 4 39 is started to drive the two-way threaded rod 40 to rotate, so that the upper and lower spreading plates 37 slide and move away from each other at the same time, and the wrinkles of the clothes are spread apart, so that it can be more intuitively judged whether the end of the spreading plate 37 is in contact with the patient's body. In addition, with the cooperation of the slide column 28 and the spring 29, a certain degree of buffering can be achieved to avoid damage to the patient's skin. The expansion plate 30 can be inserted into the patient's mouth, and then the motors 3 33 on both sides are started to drive the threaded rod 2 32 to rotate, so that the two expansion plates 30 slide and move away from each other at the same time, so that the patient's mouth can be slightly opened to avoid the situation where the patient's teeth bite the tongue due to the closure of the patient's mouth when the patient enters anesthesia. ;
